The ZephyMote V2 provides ±1°C accuracy for temperature readings and ±5% accuracy for humidity measurements within the 20-90% range. These professional-grade sensors deliver reliable data for confident decision-making throughout the year.

The wireless transmission reaches up to 100 meters in open areas without obstructions. Walls, trees, and buildings may reduce this range, but most users experience excellent connectivity within typical home and yard setups for reliable monitoring.

Yes, the outdoor sensor features weather-resistant construction designed for year-round outdoor exposure. It withstands rain, snow, and direct sunlight, though mounting in a shaded area can extend sensor lifespan and maintain optimal measurement accuracy over time.

The ZephyMote V2 Weather Station updates measurements every 16 seconds, providing near real-time weather data. This frequent refresh rate ensures you always have current information for tracking rapidly changing conditions and making timely outdoor activity decisions.

No internet required—the ZephyMote V2 operates completely independently using 433MHz wireless transmission between sensors and display. This standalone functionality ensures reliable weather monitoring even during power outages or internet service disruptions at your location.

The indoor display uses 3 AAA batteries while the outdoor transmitter requires 3 AA batteries. Battery life typically lasts 12-18 months depending on usage. Optional 5V power adapter available for the indoor unit eliminates battery replacement needs.

The standard ZephyMote V2 package includes one outdoor sensor. The system's 433MHz frequency and transmission protocol are designed for single-sensor operation, ensuring optimal accuracy and eliminating signal interference for the most reliable weather data collection.

The barometric pressure sensor tracks atmospheric trends over time. Rising pressure typically indicates improving weather, while falling pressure suggests approaching storms. The ZephyMote V2 analyzes these patterns to forecast conditions 12-24 hours ahead with impressive accuracy.
